PAPER DRIER.,

Application led'June 9,1924. Serial No. 718,828.

T 0 all whom, t lmay concern:

Be it known that I, CHARLES W. SlrAn'rLE, a citizen of the United States, residing at Middletown, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Paper Driers, of which the following is a specification, reference. being had therein to the accompanying drawings.

This invention relates to improvements in The main object of the invention is to provide an apparatus for drying the paper, as the. paper web is delivered from the Fourdrinier, or paper forming machine, in which the drying process will be facilitated by causing the web to travel in a ser entine path over a series of drier units eac comprised of a plurality of sets of drier rolls, one set of rolls being disposed above the other in' horizontal planes parallel one with another; each unit as a-whole being arranged in a plane inclined to the vertical and suitably spaced from adjacent units; the drier paper .driers rolls of each unit being entrained one with another by gearing driven from va common drive shaft; the apparatus as a whole being supported on a suitable frame which serves to coordinate the different units in a unitary machine. i

By the arrangement described the apparatus as awhole stands at much eater elevation than the common, longtu inally arranged paper driers, thus adapting the machine to be confined to less floor space and at the same time providing for a larger volume of air to act on the paper web in its course of travel over the rollers, theair lalso being caused to circulate more freely over and between the rolls and over both surfaces of the paper, and thus to facilitate the drying process.

In the accompanying drawings of the` improved apparatus:

Fig. l is a side elevation of the drier ap` paratus; p n

Fig. 2 is a broken horizontal sectional Fig. 3 is a detail of one of the drier rolls, and v Fig. et isa detail ing the drier rolls.

Fig. 5 is a detail of one of the side frame units.

As here shown in a preferred construcof the gearing for drivtion, the apparatus as a whole is supported in suitable frame comprising horizontal and vertical frame members 1 and 2 in which 'ournal boxes are provided, as illustrated at. 3, for the drier rolls 4 whirh are traversed in a serpentine path' by the paper web 5 as it` passes from the forming machine, a detail of which is shown at 6. lSteps 7, platforms, or foot boards 8, and hand rails 9 are provided to afford convenient access to all parts of the apparatus by an attendant.

The frame is built up in sections, a frame i unit being illustrated in- Fig. 5, the frames for the -dilferent drier units being also joined one to another so that an entire side frame for the complete apparatus is tied to ether.

ach of the drier rolls is supported on a journal 10, having its bearings in o-p osite journal boxes 3, an end of the journa projecting through the bearing on one side of the machine and haying secured thereto a gear l1 of the required 4diameter vto mesh with an equal gear with the opposite roll of the set and also with an equal gear of the opposite roll of the adjacent set of rolls above or below, as the case may be, thus causing the rolls of each set to be operated one in clock-wise and the other in counter-clockwise direction, and the paper web, passing over one roll and under the other roll of a set, to move continuously in the forward direction. The rolls of each unit are driven, as here. shown, by a gear 12, secured to a drive shaft 13, and meshing with a gear 11 on'the journal shaft of the lowermos't roller 4 of each drier unit.

From the foregoing descripiton of the improved drier apparatus, it will be obvious that the paper web travels over the drier rolls in a serpentine path over the series of drier units, that open spaces are thus formed between the units through which the air will circulate freely in lts general rising movement, the air being usually artificially heated to facilitate the drying process. Thus a much larger volume of air is brought to act upon both sides of the paper, taking up the moisture from the paper vby saturation or evaporation `much more rapidly than is possible in paper driers of common construction.

From the viewpoint of construction and operation, the improved apparatus is also a highly effective mechanical organization,

the general design and arrangement of parts of the machine in its entirety being such as will insure dependable operation and effective functioning of the apparatus.

Having described my invention, I claim:

1. A paper drier, including in combination, a series of drier units each comprising a plurality of sets of drier rolls, arranged one set above another' in parallel horizontal planes, horizontally opposite rolls of the unit being operable in contra-directions and adapted to be traversed in a serpentine path by a paper Web.

A paper drier, including in combination, a series of drier units spaced one from another and extended in planes inclined to the vertical and parallel one with another, each unit comprising a plurality of sets of drier rolls, arranged one set above another ersed in a serpentine path by a paper web. v

3. A papel.' drier, including in combina.- tion, a series ol drier units spaced one from another and extended in planes inclined to the vertical and parallel one with another, each unit comprising a plurality ol' sets of drier rolls arranged one above another, the rolls of a set being geared one to the other, and one of the rolls to a roll 0f an adjacent set whereby the opposite corresponding rolls of a unit are caused to rotate in contra-directions to adapt a paper Web to traverse the unit in a serpentine path.

1n testimony whereof I aflix my signature.

CHARLES W. SHARTLE.
